It's not clear how you can say "no other changes" and follow on with "of course this also implied some dietary changes, like no bread anymore due to sodium contents".
That seems like a potentially significant change you're ignoring.
fair enough, although I personally don't think that cutting bread and eating more potatoes is that big of a difference overall, it is a difference so hey, for all I know that might have influenced things. As I was saying above, n=1 after all.
It has been suggested that "leptin resistance is considered a primary risk factor for obesity. It has been hypothesized that dietary cereal grain protein could cause leptin resistance by preventing leptin from binding to its receptor."
"Similar to what is observed in chronic inflammation, chronically elevated leptin levels are associated with obesity, overeating, and inflammation-related diseases, including hypertension, metabolic syndrome, and cardiovascular disease."[2]
